Just so, why do we heat to constant mass?
Heat to constant mass to ensure all of the water of crystallisation is removed. Heating to constant mass involves heating the same for several minutes, weighing it and repeating this until two consecutive mass measurements are the same.
Also Know, does Heat Affect Mass? Mass. When you heat the temperature the atoms in the object move faster. So that's how the mass of an object changes.
Subsequently, question is, why is it important to heat the crucible to a constant mass?
Why was it important to heat the empty crucible to a constant mass before adding the hydrated salt? The empty crucible is heated to remove moisture and ensure that the crucible is completely dry as any water present may affect the reading.
Why must objects be cooled before weighing?
Objects should be cooled before their mass is determined on a sensitive balance because it could damage the balance. Also, because it would give you wrong reading of the mass. Hot objects would warm the air around it. It is always recommended to weigh the masses of objects that are in room temperature.
